# DELETE /deviceUpdate/{instanceId}/management/deviceClasses/{deviceClassId}

`DELETE /deviceUpdate/{instanceId}/management/deviceClasses/{deviceClassId}`

Deletes a device class. Device classes are created automatically when Device
Update-enabled devices are connected to the hub but are not automatically
cleaned up since they are referenced by DeviceClassSubgroups. If the user has
deleted all DeviceClassSubgroups for a device class they can also delete the
device class to remove the records from the system and to stop checking the
compatibility of this device class with new updates. If a device is ever
reconnected for this device class it will be re-created.
